这里写图片描述

Spring Cloud是Spring总多的Project中的一个,它提供了一整套的工具帮助系统架构师们在进行分布式设计的时候可以拿来即用, 在创建和发布微服务时极为便捷和有效。本系列文章将会使用最简单的例子和最为容易的方式来学习Spring Cloud。本文将会介绍如何使用Spring Cloud的Eureka实现服务发现。

构成

Spring Cloud由很多子项目构成,为了介绍方便,挑出一些项目中常用的进行如下构成。

这里写图片描述

具体各个Service之间的关系不再一一展示,将其粗暴地分为框架类服务(Spring Cloud服务)也业务逻辑服务两种,各服务功能和实现简单如下说明。

项目 详细
Config Service Spring Cloud Config:统一配置管理服务
Dashboard Service Hystrix Dashboard
Api Route Service Zuul:Api Gateway
Discovery Service Eureka:服务发现
User Service RESTFUL的用户相关的服务
Org Service RESTFUL的组织相关的服务

本文将会用最简单的方式来介绍如何使用Eureka进行服务发现的,以及Spring Cloud中使用Eureka是如何方便。

Sprint Boot项目

创建一个Spring Boot项目,详细不再介绍, 集体方法可以参看如下文档。

Eureka Server

Pom设定

需要将 <artifactId>spring-cloud-starter-eureka-server</artifactId>加入到POM中,可以参照如下Pom示例。

注解

加入注解EnableEurekaServer,在Spring boot的应用中只需这样一行就将EurekaServer引入其中。

package com.liumiaocn.demo.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class DiscoveryserviceApplication {

    public static void main(String[] args) {
        SpringApplication.run(DiscoveryserviceApplication.class, args);
    }
}

设定文件

使用bootstrap和application两个设定文件来进行相关设定,入门时为了更加快速,使用最少的设定文件和设定语句,基本上只有不可或缺的才会加上,入门之后详细内容参看spring cloud官方文档即可。application.properties文件的最少作如下设定即可。

server.port=8801
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
项目 详细
server.port Eureka Server的Dashboard所使用的port
eureka.client.register-with-eureka 是否要注册到服务器端,因为此处为Eureka Server,所以设定为false
eureka.client.fetch-registry 是否从服务器端取得注册信息,因为此处为Eureka Server,所以设定为false
eureka.client.serviceUrl.defaultZone 缺省设定,此处Default为http://localhost:8761/eureka/,但实际时因为Port较多,最好统一排番,统一管理。
